Anemia is one type of red blood cell disorder. A lack of the mineral iron in your blood usually causes this disorder. Your body needs iron to produce the protein hemoglobin, which helps your red blood cells carry oxygen from your lungs to the rest of your body.
Heat transfer refers to the physical process by which heat energy moves from one area to another. The Heat Transfer Methods figure above illustrates various heat transfer methods. Branches above the fire are receiving heat by convection and radiation.
How Does Thermal Energy Transfer? Thermal energy transfers, or moves, between objects in three ways: radiation, conduction, and convection. Let's look at what these words mean and some examples of each. Radiation. Radiation is how something gains heat without touching the heat source. It's how planet Earth stays warm. The sun radiates thermal energy, and the earth absorbs it.
